C Specification

void glReleaseShaderCompiler(

void);

Description

For implementations that support a shader compiler,
glReleaseShaderCompiler
frees resources allocated by the shader compiler. This is a hint from the application
that additional shader compilations are unlikely to occur, at least for some period of time,
and that the resources consumed by the shader compiler may be released and put to better use
elsewhere.

However, if a call to glCompileShader
is made after a call to glReleaseShaderCompiler, the shader compiler must be restored
to service the compilation request as if glReleaseShaderCompiler had never been called.

Notes

Shader compiler support is optional, and thus must be queried
before use by calling glGet
with argument GL_SHADER_COMPILER. glShaderSource,
glCompileShader,
glGetShaderPrecisionFormat, and
glReleaseShaderCompiler will
each generate GL_INVALID_OPERATION on implementations
that do not support a shader compiler. Such implementations instead offer the
glShaderBinary
alternative for supplying a pre-compiled shader binary.

Errors

GL_INVALID_OPERATION is generated if
a shader compiler is not supported.
